The Registrar Department of Barclays Bank DCO (Dominion, Colonial and Overseas) was established in 1959. It was the first Registrar Office to be established in Nigeria to compliment the Nigerian Stock Exchange which was also established about the same time. The Registrars remained a department in the renamed Barclays Bank of Nigeria Limited, a wholly owned subsidiary of Barclays Bank International Limited. However, in 1979 when Barclays Bank sold 50% of her shareholding in the Bank to Nigerians, the Bank’s name changed to UNION BANK OF NIGERIA LIMITED while the remaining shareholding of Barclays Bank was disposed off in 1989. Up to 2003 Union Bank of Nigeria Plc retained the Registrars as a Department.
